BRAKE FOR HORSE-POWERS OR SPE ED-REGULATORS.

SPECIFICATION forming part of Letters Patent No. 434,266, dated August 12, 1890.

Application filed April 1.4, 1890. Serial No. 347,852. (No model.)

To all whom it may concern:

Be it known that We, LEONIDAS GRAY and ALBERT Y. GRAY, of Middletown Springs, in the county of Rutland and State of Vermont, have invented a new and useful Improvement in Brakes for Horse-Powers or Speed- Regulators; and we dohereby declare that the followingis a full, clear and exact description of the same.

Our invention relates to a brake device particularly applicable to a horse-power and to be used in connection with a governor or speed-regulator for the same, though we do not desire to limit ourselves to this special application of the invention, as it may be found useful in other situations.

In the accompanying drawings We have shown in Figure 1 the device applied to a horse-power which is provided with a form of governor or speed-regulator; and in Fig. 2 we have shown which is the subject of the present application, on an enlargedscale.

In the drawings we have shown but a part of the horse-power, this being represented at A, the fly-wheel being shown at B. This wheel is provided with a speed-regulator or governor, which may be of any ordinary or improved construction, and from this regulator extends a cord-connection ct, leading to the end of a brake-lever O, which is pivoted at the point I).

The brake-block is shown at D, and maybe of any ordinary or improved construction, and this is pivoted to a bar 0, which in turn 'is pivoted at its lower end to the standard (Z.

The upper end of the bar is free. Between the brake-lever O and the brake-block is a link e, and thus it will be seen that as the end f of this lever is drawn on when the speed of the power is beyond what it should be, this will cause the link to press upon the block and as the block cannot be pressed downwardly by reason of its connection with the pivoted bar, it will be seen that it will move squarely against the face of the drivthe particular improvementing-wheel, and thus retard its action or stop it altogether. It will also be seen that when the end of the brake-lever is slightly depressed the power of the brake-block will be slight and will gradually increase as the end of the lever is drawn on, so that there will thus be no sudden shock from the instant application of the brake-block to the surface of the wheel. The joint connection of the brake-block is also advantageous inasmuch as it always strikes the surface of the wheel squarely without regard to the size of the wheel or the angle of the brake-lever, while in the case of a rigidly-held brake-block the block does not act squarely against the face except in certain situations.

It will be understood that when this brake device is used in connection with other forms of devices than the horse-power shown the parts may be supported by different devices, though the parts referred to are representative of similar parts in other machines.

We do not limit ourselves to the use of a governor, as the brake-lever maybe operated by hand or in any other suitable way.

WVe claim as our invention 1. In combination with abrake-lever, as C, a bar pivoted at its lower end and having its upper end free, a brake-block supported by said bar, and a link-connection between the block and brake-lever,substantially as described.

2. In combination with a brake-lever, as O, a governor in connection with said lever, a brake-block, a pivoted bar supporting said block, and a link-conneotion between the said block and lever, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
